Description
Technical field
The utility model relates to a kind of milling machine, especially a kind of milling machine that can quicken.
Background technology
In field of machining, the processing of gear is all carried out mill teeth by milling machine usually.It during the milling machine mill teeth cutting continuously.Milling machine is controlled by cage chair, and when just beginning to cut, cutting output is big, need bigger cutting force, so rotating speed is slower, makes cutting that enough cutting force be arranged.When cage chair moves to the centre position by the time, gear machines substantially, at the cage chair latter half, the cutting output of gear is very little, the cutting force that needs is also very little, but because the restriction of milling machine transmission, the gearratio that transmission in reduction box remains when beginning is identical, the internal structure of reduction box as shown in Figure 1, it is provided with power shaft 1 and output shaft 5, power shaft 1 and output shaft 5 all rotate on the shell 2 of the reduction box that connects, be connected with driving wheel 3 on the power shaft 1, be connected with driven pulley 4 on the output shaft 5, the number of teeth of driving wheel 3 is less than the number of teeth of driven pulley 4, thereby reach the purpose of deceleration, because little in the post-production amount of Gear Processing, so cutting force has bigger residue, therefore makes working (machining) efficiency lower, especially when the batch machining gear, its working (machining) efficiency is low particularly evident.
The utility model content
The utility model is exactly to solve the lower problem of traditional milling machine batch machining gear efficiency.
The technical solution adopted in the utility model is: the milling machine that has acceleration mechanism, it comprises reduction box, be provided with power shaft and output shaft in the reduction box, be fixed with driving wheel on the power shaft, output shaft is provided with driven pulley, driving wheel and driven pulley driving coupling, output shaft drives milling cutter and rotates, it is characterized in that also being fixed with on the described power shaft acceleration driving wheel, output shaft is provided with the acceleration driven pulley, quicken driving wheel and add to go back the driven pulley driving coupling, the number of teeth of quickening driving wheel is less than the number of teeth of quickening driven pulley; Driven pulley rotates with output shaft with the acceleration driven pulley and connects; Driven pulley is provided with the clutch tooth in the side in opposite directions with the acceleration driven pulley, be provided with castle wheel between driven pulley and the acceleration driven pulley, two sides of castle wheel are provided with and driven pulley and the suitable clutch tooth of acceleration driven pulley side clutch tooth, common formation clutch, castle wheel connects with output shaft spline gap, makes castle wheel to endwisely slip and can not radially rotate along output shaft; Castle wheel is provided with fork pockets, is provided with shift fork in the fork pockets, and the other end of shift fork connects with the shift fork drive unit, and shift fork can laterally be moved.
Adopt technique scheme, when the beginning mill teeth, castle wheel connects with driven pulley by the clutch tooth, driving wheel drives driven pulley and rotates, and driven pulley drives castle wheel by the clutch tooth and rotates, and castle wheel connects with output shaft by spline, therefore drive the output shaft normal rotation, realize normal process; When the cage chair of milling machine turns to the centre position, start the shift fork driving mechanism, shift fork laterally moves, shift fork drives castle wheel and laterally moves, castle wheel separates with driven pulley, at this moment driven pulley still rotates, but connecting because driven pulley rotates with output shaft, is invalid transmission therefore, and the continuation of shift fork is moved, castle wheel is connected with the acceleration driven pulley by the clutch tooth, at this moment quicken driving wheel and will drive and quicken driven pulley and rotate, quicken driven pulley and drive output shaft by castle wheel and rotate, because the number of teeth of quickening driving wheel is more than the number of teeth of quickening driven pulley, therefore the rotating speed of output shaft will be faster than input shaft rotational speed, thereby reaches the purpose of acceleration.
Above-mentioned shift fork drive unit comprise screw mandrel, with screw mandrel fit screw rod nut, decelerator and with the drive motors of decelerator driving coupling, screw mandrel is rotatably connected in the outside of reduction box, one end and the feed screw nut of shift fork are affixed, and screw mandrel one end connects with the output shaft of decelerator.
In sum,, when the cage chair of milling machine turns to the centre position, start acceleration mechanism, thereby make reduction box become accelerating chamber, thereby realize rapid processing, reach the purpose of raising the efficiency because the utility model is provided with the mechanism of driving up in reduction box.
